FriendInviter

FriendInviter is a web based application that can be used to, well, wait for it: Invite Friends :P. The goal of the application is to allow a user to invite a maximum of 3 of their friends using their email addresses. Here are some requirements:

1. Initial user can be either hardcoded or seeded manually in the application from a console etc.
2. Initial user sends out an email invite to 3 of his/her friends aka Recepients.
3. Recepients receive email invitations to join FriendInviter.
4. Upon acceptance of each invite, the person who sent the Invite is credited with points. Each successful invite yields 50 points.
5. If all 3 invites are successfully accepted, a bonus of 200 points is also awarded.
6. Invites should be valid for a maximum of 15 minutes.

• Loop Recursively Until no Directories are left to loop over.

• Use File.read to read the YML file one at a time.

• require 'yaml' module to start using it.

• Use the YAML module's load method to convert the YAML into a Ruby data structure, ie: Hash

Let's build a Recent File Tracker

• Implement a Class, name it RecentFiles

• You can start implementing your class from 2nd line onwards.

• You can run the test code, which will test your code using the following command: rspec file_name.rb

• You can replace the file_name.rb with your actual file which you are working with.

• If you get any errors such as rspec not found etc, please do: sudo gem install rspec

• The class should be able to handle the following scenarios:

  • Output a list of most recent accessed files.
